The variable CPACK_DEBIAN_PACKAGE_RELEASE has to be in the form

Without this change cmake 3.10 emits error.
This was dead code that did never work, and most of it was boilerplate that
you can steel in 15 minutes from any existing math inset. Apart from that it
did contain a pointer to InsetXYMatrix which would create the same problems
we saw with the macros.
This patch improves the cmake bundling process:
- reworked bundle handling for OS X: only when installing resources are copied, otherwise
only the smallest bundle is built
- on OS X, the utility programs (tex2lyx) are now installed in the right location
- it removes some unneeded BUNDLE DESTINATION
- it provides a basic support for QT plugins inclusion
- it properly builds a disk image on OS X (only the background image is missing)
- it fixes the library paths for all executables (not only LyX)
- Use the COPYING file for cmake install license
